I investigated a bit about this prob, i have the same, i switch error_reporting(E_ALL) and still there was no error message displayed, then i saw a comment line in install/index.php with the same var. I uncommented it and still no error message... Im sure the prob is when the dbmanager call a connection to mysql, i gave the root password to XOOPS in dispair to get thing work... Maybe if i can manage to see the error message when the dbmanager try to connect ill be able to figure why the error occur while trying to connect, but from now on I cant figure out how to display error message from XOOPS installation, i checked the trouble shooting section but still has i mentioned in this message it wont show any error message, and my apache is not blocking them because if i put jerk in the code i get error from php...

I got the exact same problem. I installed XOOPS on 3 other computer (not the 2.5 but the 2.5 RC, and one 2.4) and no problems.

Now running with the same configuration has VI_Knigth i get the same problem. Is there a way to get at least an error messsage that explain why it crash. I mean a blank page is just frustrating, migth be good for a running site but for the installation process it migth be usefull to know what is wrong, ill look in the source and start debug, ill give you news about it...
